MORPHING BY SURFACE INTERIOR 2

This function allows the user to morph a surface by selecting a control point within the surface domain.  The user may morph the entire surface or a region on the surface.

 

·         Select a surface using the function provided in SELECT SURFACE dialog box.

·         After a surface is selected, the dialog box as illustrated in Figure 6.5.4 is displayed.

·         The drop down button allows the user to select the type of constraint for morphing.  The description of each constraint types is discussed in Section 5.1.15.

·         If REGION is selected, the SELECT MORPH REGION button is enabled for the user to select two diagonal points on the surface to define the morphing region.

·         Click on the SELECT CONTROL POINT button to select a point on the surface (or in the region if the REGION option is selected) as the control point. After point is selected, a morphing vector and U-V line are plotted at the control point.  The user may click on the left mouse button following by moving the cursor to view the morphed U-V line in dynamic mode.  When a desired shape is obtained, the user clicks on the left mouse button to accept the morphed surface.  The surface is updated according to the new U-V lines.

·         The user may toggle on checkbox of the DEFINE MORPH DIRECTION option to define a new morphing direction.  Detailed description about this option is discussed in Section 5.1.15.

·         UNDO aborts the last morphing operation.  RESET sets the surface back to its original shape.
